-
Offers practical examples for easy understanding
-
Browser-based and user-friendly interface
Examples
-
1 STS1 (signal) equals 1800 modem (28.8k) units.
-
2 STS1 (signal) equal 3600 modem (28.8k) units.
Common Use Cases
-
Comparing SONET backbone data speeds to legacy dial-up modem rates.
-
Estimating performance differences when planning network upgrades.
-
Analyzing historical broadband speeds for telecom infrastructure.
-
Assessing bandwidth limits for legacy systems and applications.
Tips & Best Practices
-
Understand that STS1 includes network overhead affecting exact throughput.
-
Use conversions for rough comparisons rather than precise bandwidth calculations.
-
Apply the tool when planning integration of new and legacy network systems.
-
Consider line conditions that may reduce actual modem speeds from theoretical rates.
Limitations
-
Conversion rates are approximations due to SONET overhead in STS1.
-
Modem (28.8k) speed represents a theoretical maximum that may not be achieved in real analog line conditions.
-
This tool does not account for variations caused by noise, line quality, or other factors.
